Mebendazole (MBZ), a benzimidazole anthelmintic and cytoskeleton-disrupting compound, exhibits antitumor properties; however, its action on ovarian cancer (OC) is not clearly understood. This study evaluates the effect of MBZ on OC cell lines OVCAR3 and OAW42, focusing on cell proliferation, migration, invasion, and cancer stemness. The underlying mechanisms, including cytoskeletal disruption, epithelial-mesenchymal transition (EMT), and signaling pathways, were explored.

Coronary artery calcification is an impediment to percutaneous coronary interventions by obstructing the device pathway or stent deployment. To facilitate percutaneous coronary intervention in such complex lesions, high-pressure balloon dilations, atherectomy procedures, and specialty balloons are used but they all come with considerable limitations and periprocedural complications like dissection and perforation. To surpass these disadvantages, intravascular lithotripsy was introduced which acts by delivering high-pressure pulsatile sonic waves circumferentially thereby destroying the calcium deposits.

Spin-Orbit Torque (SOT) Magnetic Random-Access Memory (MRAM) devices offer improved power efficiency, nonvolatility, and performance compared to static RAM, making them ideal, for instance, for cache memory applications. Efficient magnetization switching, long data retention, and high-density integration in SOT MRAM require ferromagnets (FM) with perpendicular magnetic anisotropy (PMA) combined with large torques enhanced by Orbital Hall Effect (OHE). We have engineered a PMA [Co/Ni] FM on selected OHE layers (Ru, Nb, Cr) and investigated the potential of theoretically predicted larger orbital Hall conductivity (OHC) to quantify the torque and switching current in OHE/[Co/Ni] stacks.

Background: Foreign body (coins, magnets, button batteries, and metallic foreign bodies) ingestion is common and causes significant morbidity and mortality in children aged six months to three years. Endoscopic removal of swallowed foreign substances is widely accepted, but sedation and general anesthesia may be required to alleviate pain and anxiety during the procedure. Dexmedetomidine is used as a sedative, hypnotic, anxiolytic, and analgesic.

We present experiments, supported by mechanically detailed simulations, establishing bulk condensation of a hard-bead fluid by a tiny population of orientable motile grains that self-assembles into a moving polarized monolayer. In a quasi-1D geometry two such layers, oppositely aligned, immobilize the condensed nonmotile component. We account for our observations through a continuum theory with a naturally nonreciprocal Cahn-Hilliard structure, whose predicted trends as a function of packing fraction are consistent with our observations.

Background: Contrast-induced acute kidney injury (CI-AKI) is one of the complications of percutaneous coronary intervention (PCI) with high financial burden and poor outcomes. Dynamic coronary roadmap (DCR) is one of the augmentation tools that can provide a dynamic clear coronary mapping with the potential to reduce contrast use and CI-AKI incidence. Herein, we aim to systematically investigate the studies that have assessed the effect of DCR on PCI outcomes.

Background: Inadequate representation of women and racial minorities in heart failure (HF) clinical trials continues to limit the generalizability of the results. This could create a disparity in treatment for future heart failure therapies and devices. The study aims to assess the representation of women and racial minorities in recent heart failure studies involving sodium-glucose cotransporter-2 (SGLT-2) inhibitors.

Article Synopsis
  • Adipsic arginine vasopressin deficiency (AAVP-D) occurs due to hypothalamic dysfunction, often linked to conditions like craniopharyngiomas, which makes management difficult since key mechanisms for regulating plasma osmolality are impaired.
  • Patients with AAVP-D can suffer from severe dehydration and elevated sodium levels (hypernatraemia), leading to frequent emergency visits despite treatment with desmopressin, an arginine vasopressin analogue.
  • A case study highlights the successful management of AAVP-D through careful water intake regulation and desmopressin administration, resulting in stable serum sodium levels (140-150 mmol/L) and no emergency visits over a three-month period.

  • The study aimed to see if using an online mental health self-assessment could reduce the time clinicians spend on assessments in the psychiatric emergency department.
  • 69 out of 168 patients participated, with those using the online assessment taking about 10 minutes less for interviews compared to the usual assessment method.
  • The online self-assessment didn't significantly impact the time needed for documentation and may be more beneficial in less urgent situations, even though it may not suit all patients in the emergency setting.

Article Synopsis
  • - The study investigates the effectiveness and safety of dual antiplatelet therapy (DAPT) in high bleeding risk (HBR) patients, focusing on how these factors are influenced by DAPT duration and different stent types.
  • - A network meta-analysis of 13 randomized controlled trials involving nearly 19,500 HBR patients found that short DAPT with durable polymer drug-eluting stents (DP-DES) is associated with lower bleeding risks while still maintaining efficacy compared to standard DAPT.
  • - The research concludes that for HBR patients undergoing coronary interventions, using a short DAPT strategy with DP-DES strikes the best balance between minimizing bleeding risks and preventing adverse cardiovascular events.

Methanotrophs are bacteria that consume methane (CH) as their sole carbon and energy source. These microorganisms play a crucial role in the carbon cycle by metabolizing CH (the greenhouse gas), into cellular biomass and carbon dioxide (CO). Polyhydroxyalkanoates (PHAs) are biopolymers produced by various microorganisms, including methanotrophs.

Background: Calcified coronary arteries encountered during percutaneous intervention increase the probability of unsuccessful procedures. Heavy calcification of coronary arteries may lead to suboptimal stent expansion. Intravascular lithotripsy (IVL) is a novel method of transmitting sonic waves in pulses, which fractures the calcific plaque in the vessel with minimal soft tissue injury.

Upgrading biomass-derived bioethanol to higher-order alcohols using conventional biotechnological approaches is challenging. Herein, a novel, magnetic metal-organic-framework-based cofactor regeneration system was developed using ethanol dehydrogenase (EtDH:D46G), NADH oxidase (NOX), formolase (FLS:L482S), and nicotinamide adenine dinucleotide (NAD) for converting rice straw-derived bioethanol to acetoin. A magnetic zeolitic imidazolate framework-8@FeO/NAD (ZIF-8@FeO/NAD) regeneration system for cell-free cascade reactions was introduced and used to encapsulate EtDH:D46G, NOX, and FLS:L482S (ENF).
